Discover the Excellence of Gear Pumps: External and Internal Options
High-Quality Gear Pumps for Every Application
Gear pumps are indispensable components in various industrial and mechanical systems, known for their ability to deliver reliable, consistent fluid flow. At the heart of many fluid transfer and metering applications, these pumps come in two main types: external and internal. Each type offers unique benefits tailored to different operational needs.
External: Precision and Power
External gear pumps are renowned for their durability and precision in fluid transfer. These pumps are commonly employed in lubrication systems for machine tools, oil pumps in engines, and fluid power transfer units. Their design features either one or two gears that drive the fluid through the system, ensuring a smooth and consistent flow.
One of the key advantages of external gear pumps is their ability to operate at high pressures, often exceeding 3,000 PSI. This capability makes them ideal for hydraulic systems where precise control and reliability are paramount. Their close internal tolerances ensure accurate fluid delivery and excellent flow control, making them perfect for applications requiring the transfer of fuels, chemical additives, and polymers.
These pumps are available in various configurations, including single and double-sealed versions, as well as magnetically driven sealless versions. This versatility ensures that they can be tailored to meet specific needs, whether it’s for high-pressure environments or applications where leak prevention is critical.
Internal: Versatility and Reliability
Internal gear pumps are known for their versatility and ability to handle a wide range of viscosities and temperatures. These pumps are suitable for transferring both thin liquids, such as chemicals, and thicker substances, including mud, asphalt, sewage, and even chocolate.
One of the standout features of internal gear pumps is their simplicity. With only two moving parts and a single stuffing box, these pumps are easy to maintain and operate. They provide a consistent discharge rate and can function in either direction, adding to their flexibility.
Internal pumps come in various metallurgies, from durable iron to stainless steel and hastelloy, as well as composite materials. They are available in sealed versions or magnetically driven sealless options, ensuring compatibility with different operational environments and requirements.
